(3) In the game of roulette, a square bet is a bet on the four numbers that form a square on the roulette table. If you bet a dollar and the white ball lands on any of the four numbers you bet on,
you win $8; otherwise you lose your dollar. Find the expected value and the variance for the
amount you'll win.
(4) If you flip a fair coin 6 times, find the probability of having
(a) exactly one head.
(b) more than one head.
(c) same number of heads and tails.
(d) more heads than tails.

In each of the cases that follow, the magnitude of a vector is given along with the counterclockwise angle it makes with the +x axis. use trigonometry to find the x and y components of the vector. also, sketch each vector approximately to scale to see if your calculated answers seem reasonable. (a) 50.0 n at 60.0°, (b) 75 m/ s at 5π/ 6 rad, (c) 254 lb at 325°, (d) 69 km at 1.1π rad.

Identify the expression equivalent to 4(x + x + 7) − 2x + 8 − 4 by substituting x = 1 and x = 2.
